This is an awesome workout, especially if you are training for a race or some other cycling event. I am spent when I am finished and I do have trouble getting through the last short sets at the end. Those 6 minutes sets with the 6 killer minutes are brutal!

Instructor Comments: Coach Troy offers lots of encouragement and training advice in this workout. He has the participants check their heart rates 1 minute after the 6 minute sets to see how far they have dropped. Most people had theirs drop 30-40 beats. The faster it drops, the more fit you are. He also suggests that the day after doing this workout should be a rest or easy day.
